Shokichi Oka is the manager of the skateboarding shop DOPE SKETCH, where Reki Kyan and Langa Hasegawa work. Although he is the manager at Dope Sketch, he still appears to genuinely care about the wellbeing of his employees, especially Reki. He can be serious, as shown when he brings up Reki's injuries after a beef with SHADOW and when he forbids Reki to take on a job while injured, instead asking Langa to go. At the same time, he demonstrates that he isn't afraid to be dramatic and tell jokes, such as when he led Reki and Langa to believe that the reason he couldn't deliver a package was due to needing to work to pay off Dope Sketch's debt. In reality, the reason he couldn't go was most likely because he had a date, but he was amused the Reki had been gullible enough to buy his lie.
